Mr. Bill Callanan:

I partly agree with the Deputy. I will ask Mr. Flynn to deal with the science of that. However, it is important to look at the two elements - phosphorous and nitrogen. Phosphorous is contributed to by septic tanks, wastewater treatment and agriculture. Nitrogen, in particular in groundwater, which is very deep water, is predominantly an agricultural issue. It is not solely an agricultural issue, but it is predominantly an agricultural one. Investment in Uisce Éireann would certainly, if necessary, impact that phosphorous piece. However, it would be less impactful in terms of nitrate concentrations and our nitrate load.
